Embodiment Construction

[0034] The technical solution of the present invention will be further described in detail below.

[0035] (1) Solve the problems caused by the development environment in the co-simulation interaction across heterogeneous operating systems

[0036] Use a common high-level language as much as possible, and write the program according to the language standard, check the original development code, and check whether the original code uses the C / C++ language standard, such as the ANSIC standard of the C language; Library compatibility issues, cross-operating system collaborative interactive programs need to use the standard library.

[0037] (2) Solve the problem of the source code library for the interactive operation of co-simulation

[0038]The compiler translates the program source code into executable code. When compiling the code, different compilers have different syntax checking rules, and the classification of syntax errors is also different. This is also the case for sta...
